WHEEL.

SPECIFICAT ION forming part of Letters Patent No. '741,877, datedOctober 20, 1903, Application filed March 19,1903. Serial No. 148594;(No model.)

Ta' all whom, it may conccrn:

Be it known that I, DANIEL BEST, a citizen of the United States,residing at San Leandro, county of Alameda, State ot' California, haveinvented an Improvement in Wheels;

and I hereby declare the following to be a full, clear, and exactdescription of the same.

My invention relates to the class of vehiclewheels, and especially tothose wheels which are to be used with heavy vehicles, such asharvesters, traction engines, road locomotives, and the like.

My invention consists in a novel construction of the hub and attachmentof the spokes ther-eto, as hereinafter fully described.

Referring to the acconpanying drawings, Figure l is a vertical sectionof the wheel in the plane of the axis. Fig. 2 is a side View, and Fig. 3is an enlarged View, of one of the hub-flanges.

As shown in my Patent No. 433,19 3, the wheel consists of an exteriorrim and a hub, this hub having two fianges which are inclined outwardlyat their peripheries, so as to form annular surfaces at right angleswith the line of the spokes, the spokes extending from these hub-fiangesoutwardly to the rim, crossin'g each other between the hub and the rimand having their outer ends secured in the rim. The hub-flanges areslotted from the edges inwardly, so that when the spokes have beenproperly fixed in the rims the inner ends may be slipped into theseslots after the looking-nuts have been placed upon the inner threadedends, and by screwing the nuts upon the inner ends and against thehubflanges the proper tension is brought upon the spokes and the hub iscentered within the rim, making a strong and durable wheel.

In my former patenta guard-ring or equivalent securing device was fixedupon the outer edges of each of the hub fianges to prevent the spokesfrom being accidentally slipped out of the slots. i

It is the object of my present invention to so construct the wheel-hubas to enable the spokes to be readily inserted and removed withoutbending and to insure them against accidental displaeement or removalfrom the slots or Channels. 4

As shown in the drawings, A is the rim of the wheel. B is the hub,having flanges 2,

the outer peripheries of which are beveled or inclined outwardly, asshown at 3. These inclined surfaces are at right angles with the line ofthe spokes 4:, which are he'aded or suitably fixed in the wheel-rim and,crossing each other, are adapted to lie in slots 5, which` are formed inthe peripheries of the hubflanges. The inner ends of these spokes arescrew-threaded, and nuts 6 and? are fitted upon them. The wheel is thenbuilt up by first placing the hub approximately central within the rimand introducing the spokes through the rim and laying the inner ends inthe slots into the hub-flanges after having first placed the nuts 6 uponthe screw-threaded inner ends of the spokes. The parts may first beloosely put together, and afterward by tightening the inner ends the hubis properly centered with relation to the rim with suficient tensionupon the spokes to make the wheel absolutely rigid. The inner or locknuts 6 may then be screwed down against the outer faces of the beveledflanges to complete the wheel.

In order to nsure the spokes remaining in proper position without thenecessity of an eXterior guard-ring -or equivalent holder, I have shownou the outer peripheries of the beveled hub flanges turned up to formrings, as at 10. These ribs may either be formed upon the inner or outeredges of the flanges,

or both; but I have found it sufficient to fit them upon one side of theflanges. The nuts being then screwed down to the proper posi tion willlie against these upturned ribs, and the spokes cannot be removed untilthe nuts have been turned back sufficiently to clear the ribs. It willbe understood that these ribs may be continuous or may be in shortsections adjacent to each of the grooves.

I have shown the edges of the ribs 10 which are contiguous to the slotsas beveled or inclined on the inner angles, so that the nuts when drawndown will fit these beveled angles and more surely lock the nuts inplace.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-- l. In a wheel the hub having fianges whose outersurfaces are beveled and forned with grooves which open inwardly fromsaid surfaces, spokes fitting said grooves, nuts by IOC which the spokesare locked in place and ribs to the hub and shoulders fo'ned upon the Iformed eontiguous to the outer edges of the hub-fianges exterioto thennts.
